ARC: [plat-axs*/plat-hsdk]: Allow U-Boot to pass MAC-address to the kernel

2018-08-27T16:00:36Z

Otherwise kernel uses random MAC which is not very conveniet. With that change in place use might set desired MAC in U-Boot with "setenv ethaddr 11:22:33:44:55:66", save environment and then from boot to boot the same MAC will be used by the kernel. One other note for this to happen it's required to pass board's .dtb in U-Boot's "bootm" command like that: ------------------->8----------------- bootm 0x82000000 - 0x84000000 ------------------->8----------------- Here 0x82000000 is location of uImage while 0x80000000 is location of either axs10x.dtb or hsdk.dtb previously loaded from SD-card, USB storage or TFTP server.

kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers

2018-04-07T10:04:02Z

GNU Make automatically deletes intermediate files that are updated in a chain of pattern rules. Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts Example 2) %.o <- %.c <- %.c_shipped A couple of makefiles mark such targets as .PRECIOUS to prevent Make from deleting them, but the correct way is to use .SECONDARY. .SECONDARY Prerequisites of this special target are treated as intermediate files but are never automatically deleted. .PRECIOUS When make is interrupted during execution, it may delete the target file it is updating if the file was modified since make started. If you mark the file as precious, make will never delete the file if interrupted. Both can avoid deletion of intermediate files, but the difference is the behavior when Make is interrupted; .SECONDARY deletes the target, but .PRECIOUS does not. The use of .PRECIOUS is relatively rare since we do not want to keep partially constructed (possibly corrupted) targets. Another difference is that .PRECIOUS works with pattern rules whereas .SECONDARY does not. .PRECIOUS: $(obj)/%.lex.c works, but .SECONDARY: $(obj)/%.lex.c has no effect. However, for the reason above, I do not want to use .PRECIOUS which could cause obscure build breakage. The targets specified as .SECONDARY must be explicit. $(targets) contains all targets that need to include .*.cmd files. So, the intermediates you want to keep are mostly in there. Therefore, mark $(targets) as .SECONDARY. It means primary targets are also marked as .SECONDARY, but I do not see any drawback for this. I replaced some .SECONDARY / .PRECIOUS markers with 'targets'. This will make Kbuild search for non-existing .*.cmd files, but this is not a noticeable performance issue.

arc: dts: use 'atmel' as manufacturer for at24 in axs10x_mb

2018-02-06T22:36:32Z

Using compatible strings without the part for at24 is deprecated since commit 6da28acf745f ("dt-bindings: at24: consistently document the compatible property"). Use a correct 'atmel,' value. Signed-off-by: Bartosz Golaszewski Acked-by: Alexey Brodkin Signed-off-by: Vineet Gupta

ARC: Enable fatal signals on boot for dev platforms

2018-01-18T18:51:27Z

It's very convenient to have fatal signals enabled on developemnt platform as this allows to catch problems that happen early in user-space (like crashing init or dynamic loader). Otherwise we may either enable it later from alive taregt console by "echo 1 > /proc/sys/kernel/print-fatal-signals" but: 1. We might be unfortunate enough to not reach working console 2. Forget to enable fatal signals and miss something interesting Given we're talking about development platforms here it shouldn't be a problem if a bit more data gets printed to debug console. Moreover this makes behavior of all our dev platforms predictable as today some platforms already have it enabled and some don't - which is way too inconvenient.

ARC: [plat-axs10x] DTS: Add reset controller node to manage ethernet reset

2017-11-15T17:40:43Z

DW ethernet controller on axs10x hangs sometimes after SW reset. Invoke the newly aded driver (reset-axs10x.c) by adding the DT bits. With this in place, we don't need the open-coded quirk in platform code, so get rid of it as well !
